In the Northern Hemisphere, the March equinox (aka spring equinox or vernal equinox) occurs when the Sun crosses the equator line, heading north. This event marks the start of the spring season in the northern half of the globe. After this date, the Northern Hemisphere begins to be tilted more toward the Sun, resulting in increasing daylight hours and warming temperatures.
The amount of daylight each day will continue to increase until the summer solstice in June, during which the longest period of daylight occurs.
